24 of the frame 14. Both of the gears 20 and 21 are formed as shown inFig. 7, in .which a tooth is shown, this tooth 30 having an open space31.011 either side thereof and a shroud 32 which coincides with thetends down into the `well in accordance with i The method of operationofthe invention -is as follows? A The shaft 17 being'driven from anysuitable sourcei'iot shown, the gear 20 rotates withrthis shaft at thesame time rotating the gear 21 by means of the teeth 80. At-the Vpitchline ofthe teeth. Apump rod 33 is secured to the bottom ,of thefranieand exsame time the weight of thepump rod and its attachedparts-iscarried on the shrouds 32 of thegears 20 and 21 which roll together epractically without friction.VA As the gear 20 turns through adistanceof 180 degrees the gear 21 is also turned through this same distance andthe pump rod 33 is lifted eX- actly twice the distance that it would bewere a cam used-having dimensions equivalent to that of thel gear. 20.This lifting is accomplished practically without friction as there is nosliding motion between the shrouds 32 of the gears 2O Vand 21andpractically no sliding `motion on tlieteeth of `these gears if they areproperly constructed. The pump head can therefore be raised and loweredwith a minimum of frictional losses `andvwith a very long stroke ascompared to the-stroke of a cam driven pump.

It will be noted that the shrouds 32 are in Aeffect cams which areheld,` and driven in rods 13, these'rods serving as! guides for a `theirproper relative position by the gears reciprocating framel. This frameis prof and-21. yObviously the gears and cams fvided with babbittedbearings so that it mightbe associated in different relationship 40slidesreadily-.onthe rods13, caps15 being"V without departing from thespirit of my 'Y provided on jeach bearingas is standard-.invention. 1 i`I`V 1practiceI in the 'art.'-`Bearing brackets 16.are. `Theconstruction of the Vhead 14C gives a rigidly secured on the rods'lrandajdrive very long bearing 4between the upper caps Y V shaft 17 turnstherein, this "drive sh'aftiloeingv 1.5and1theflower caps 15 so thatthere is 45 connected by meansof a couplinglS with little liabilityofthe pump jamming or get- 'an auxiliary drive shaft19'driven'fromanytingoiitof alineinent., v'lhefgears 21 and l suitablesource of power...`Keyedxon the? `22,1,beiiig` o ffidentical construction caribe shaft 17is a drivinggearu20.
